Embodiment 2

[0096] Such as Figure 16 to Figure 20 As shown, the difference between this embodiment and Embodiment 1 is that the pressure relief hole 313 is omitted, so that when the temperature-sensing wax valve 33 drives the sealing rod 32 to move axially in the valve body 31, the sealing rod 32 can be positioned sequentially along its axial direction. Distributed low-temperature communication positions, suitable temperature blocking positions and high-temperature pressure relief positions, wherein, when the sealing rod 32 is in the low-temperature communication position, the external oil port 311 is connected to the oil outlet 312 and the external oil port 311 is disconnected from the assembly space 36; When the sealing rod 32 is in the temperature-appropriate blocking position, the external oil port 311 and the oil outlet 312 are disconnected and the external oil port 311 is disconnected from the assembly space 36; when the sealing rod 32 is in the high temperature pressure relief posi...

Abstract

The invention relates to the field of vehicles, and discloses a fuel filter upper cover, a fuel filter and an engine fuel supply system. According to the upper cover of the fuel filter, the top exhaust hole used for installing the exhaust valve is formed in the top of the upper cover body, so that the exhaust requirement is met; the structural strength of the upper cover is improved through the first annular boss and the second annular boss, meanwhile, a first inner side reinforcing rib is arranged on the inner top wall of the upper cover body, one end of the first inner side reinforcing rib is connected to the outer circumferential wall of the first annular boss, and the other end of the first inner side reinforcing rib is connected to the inner circumferential wall of the second annular boss. The influence of the top exhaust holes on the structural strength of the upper cover is made up through the first inner side reinforcing ribs.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an upper cover of a fuel filter, a fuel filter and an engine oil supply system. Background technique [0002] The fuel filter is installed on the car, and the working environment is relatively harsh. For example, when the vehicle is bumped, the vibration is large. Although a vibration-damping structure is provided, there is still a high requirement for the structural strength of the fuel filter shell. [0003] The existing fuel filter housing has the disadvantage of insufficient strength, so that the service life of the fuel filter is affected. Contents of the invention [0004] The object of the present invention is to provide a fuel filter upper cover, a fuel filter and an engine oil supply system, which can improve the structural strength of the filter housing. [0005] For reaching this purpose, the present invention adopts following technical scheme: [0006] A fuel filter upper ...
